Rack mounted (fix gain or programmable) current transducers. Made for ultra high accuracy. 14 models. DC, AC pulse currents' measurements from 40 to 24000 ADC nominal with galvanic isolation. Excellent linearity, from 1 to 10 ppm. High resolution. Initial offset: < 2 ppm. Very low offset drift: from 0.1 to 0.6 ppm/K. Overall accuracy @ Ipn @ +25°C: between < +/- 3 ppm and < 12 ppm. Wide frequency bandwidth from DC up to 500 kHz (+/- 3 dB). Closed-Loop Fluxgate technology. Electrostatic shield between primary and secondary in the heads. Power supply 100-240 VAC, 50-60 Hz. Products made up of one measuring head in a side and one separated electronic in the other side connected together via a cable. Operating temperature range from +10 to +40°C for the electronics and from 0 to +55°C for the measuring heads. D-Sub 15 female connector used for the analogue output. D-Sub 9 male connector used for the status output. Really quick response time (from <1 µs to <2 µs). 600 A and 2000 A models are programmable in the needed range thanks to some programming plugs to add on the measuring heads. 5 measuring heads are available according to the current to measure and to the aperture needed for the primary conductor (from 25.4 mm up to 150.3 mm diameter).
